This paper examines Zara's success from the perspective of time-based competition. While most of people attribute Zara's time-based success to its extremely short lead time and regard Zara as a benchmark for speed, this paper argues that a fast speed is indispensable but not sufficient to time-based success. Based on a qualitative analyze of Zara's operations, tactics and strategies, the paper indicates...
The phase-shifting interferometer using a wavelength tunable laser is applied to test large optical components. A method based on the one-dimensional Fourier transform in time domain to calibrate the phase in wavelength-tuned phase-shifting interferometer is presented. It solves the problem that how to control the phase-shifting step to a certain value at different interferometric cavity lengths when...
In this paper we consider the capacitated multi-item lot sizing problem with setup times. The problem is to schedule N different items over a horizon of T periods with the objective to minimize the sum of setup cost and inventory holding cost. To achieve feasible high quality solutions, we propose a hybird solution approach which integrates nested partitions and relax-and-fix. Nested partitions is...
When considering on planning and designing of Urban Comprehensive passenger transport hub in China, it just aims on convenient construction for various transport modes. The need of passenger is seldom taken into account, which lead to single-mode and flat hub adding the burden of passenger when transfer. The fundamental object of transport hub design is mean to meet passenger needs, which is also...
E-supply network coordination (e-SNC) is a new structure obtained by information technology, automation of different echelons' behavior, and the market globalization. The information flow and cooperation among echelons are two key drivers in SN. Here, supply network is considered as a collection of agent-mediated decision and coordination mechanisms in a Web-based environment. The proposed coordination...
In order to quickly determine and control the chaotic oscillation in supply chain system, to enhance the prediction accuracy of supply chain demand, and ensure the stability of supply chain systems, using fuzzy neural networks based on chaotic time series, sub-phase space is rebuilt by the demand time-series of supply chain system. Calculating the phase-space saturated embedding dimension and the...
To meet real-time requirements of communication between various testing entities, complex virtual testing system is constructed base on heterogeneous networks environment. Bridge method is the main approach for HLA-DIS inter-protocol connection. It solves the problems of interoperation but becomes the bottom-neck of the whole testing system. In application environment, the performance analysis method...
In complex rule flow logic verification, simulation based testing approach is one feasible way which tries to go through all the feasible paths. As the baseline, the total number of feasible paths is usually desired to know although it is usually a huge number. The calculation algorithm of feasible paths in a rule flow is proposed in this paper. Using air cargo loading planning rule as an example,...
The rural development issue is a bottleneck restraining the development of China economy. How to promote the sustainable development of agriculture, improve the rising rate of farmers' income, and finally achieve the common prosperity by agricultural scientific and technological innovations, is an important issue for China's economic development. By studying the nature of different modes' operation...
To enhance the success rate of merger and acquisition, the acquiring party should make due diligence investigation into the target enterprise's counting materials and financial situations when filtering the target enterprises. Meanwhile, the acquiring party must thoroughly analyze the target enterprise's motive for selling, making sure that all the financial resources of the target enterprise well...
WSN research focuses on low cost, low consumption and high efficiency, which are also important parameters for network performance. One of the main objectives of wireless sensor network design is to improve the energy efficiency. How to efficiently utilize sensor nodes to prolong the lifespan of a wireless network has long been a research topic. This paper deals with influence to the fusion of part...
Based on computer vision principle and digital image differential detecting technology, we present a real-time method of vehicle's speed detection. First, calibrate parameters of camera, capture digital signal of images and take pre-processing on images. Then, select background image and set linear projection of speed. Finally, detect the moment of passing the linear projection of speed, and compute...
For a multiple-segment flight of passenger aircraft, the primary objective of commodity load planning is to improve the operational efficiency of the whole journey. Unfortunately the objective can not be measured due to the unavailability of down-line stations shipment information. Traditional optimization algorithm can not be directly applied. Rule based optimization approach is proposed in this...
We present an innovative approach for clustering retail customers using semi-supervised geographic information. The approach aims at clustering (or segmenting) customers not only depending on their age, spending, etc., but also on their dwelling, which can discover useful customer patterns for the retailer's marketing strategy. In real retail applications, unsupervised clustering faces the problem...
With the increasingly intense competition, China's supermarket retailers call for a complete, stable and practical customer segmentation approach to utilize consumer data so as to effectively customize the firm's marketing efforts and targets. We propose a novel three-step segmentation framework to reveal the consumer's demographics, behavioral, psychological characteristics in supermarket shopping,...
This paper studies the forming process of customer value based on grounded theory. Through mining the factors and analyzing the relationship between them during the customer value formation, the model of customer value is constructed in a business to customer market. At the same time, the paper build the measuring model and propose four types of customer measurement: the measurement of each factor...
Temporary gate shortages and stochastic flight delays are common problems that often occur simultaneously in real-time airport operations. In this study the aim is to propose a gate reassignment model designed to deal with temporary gate shortages with stochastic flight delays. This is done by allowing for violation of gate reassignment constraints in the model. Numerical tests, based on the operations...
Highway transportation industry plays an important role in national economic development. In this paper cointegration theory is used to analyze the quantitative relationship between China's highway transportation industry and national economic development. At first, literature overview is taken for the relationship between highway transportation industry and national economic development. Secondly,...
The growing complexity of multimodal logistics operations, especially those involving port operations and road haulage, represent a significant number of challenges in terms of track and trace, security, information sharing and visibility. This paper investigates the feasibility of implementing Dedicated Short Range Communication (DSRC) wireless technology in multimodal logistics operations. Tasks...
This paper explores the problem of hospital stock-piling of critical medical supplies in preparation for a possible influenza pandemic.We consider a regional network of hospitals that have mutual aid agreements in place such that they may borrow or lend supplies from each other during medical emergencies. We assume that the attack rate is a random variable with known distribution and that the demand...
